Definitions

  • the present technology pertains to radio frequency (RF) antennas, and more specifically pertains to switchable near-field and far-field RF antennas.
  • RF radio frequency
  • Radio frequency (RF) signals are often used in RFID systems in order to communicate with one or more tags, for purposes such as security or tracking.
  • an RFID system uses a transceiver to broadcast an interrogation signal, which is received by any operable RFID tag within the operable range of the transceiver.
  • each RFID tag Upon receiving the interrogation signal, each RFID tag transmits a response signal that encodes unique tag identification information and other stored data.
  • RFID tags can be classified as either passive or active, depending on how they are powered - passive RFID tags are powered via an onboard DC converter that extracts energy from the interrogation signal, and active RFID tags are powered by an onboard battery.
  • simply receiving a response signal is sufficient, as it indicates that the RFID tag (and any person or object associated with the tag) corresponding to the response signal is located within the boundaries defined by the range of the RFID transceiver. Greater granularity may be provided by transmitting each response signal at a known signal strength, given that signal strength decreases in a predictable manner. As such, the distance between the RFID transceiver and a source tag can be approximated by analyzing the signal strength of the response signal received at the transceiver.
  • RFID systems may be divided into near-field systems and far-field systems, each exhibiting unique properties and requiring a specific type of antenna.
  • the most immediately observable distinction between near-field and far-field is the separation range between tag and transceiver over which the RFID system remains operable.
  • Near-field systems often found in card readers and other close proximity applications, are constrained to a separation on the order of inches and are polarization agnostic.

  • the access control system further transmits position information corresponding with one or more of the location of the wireless asset and the direction of the wireless asset to a cloud controller, wherein the cloud controller is configured to receive position information from a plurality of networked asset control systems.
  • scanning the RFID tag further comprises oscillating the antenna module between a near-field scanning mode and a far-field scanning mode, wherein the near-field scanning mode corresponds with activation of the near-field antenna, and the far-field scanning mode corresponds with activation of the far-field antenna.
  • the return signal comprises signal strength and phase information associated with the RFID tag.
  • the near-field antenna is a UHF near-field loop antenna.
  • Disclosed is a method for tracking a wireless asset comprising scanning, using a transceiver, an RFID tag of a wireless asset, wherein the transceiver comprises an antenna module including a near-field antenna and a far-field antenna, receiving one or more return signals from the RFID tag, and determining a location of the wireless asset based on the one or more return signals.
  • the near-field antenna is a subset of the far-field antenna.

  • scanning the RFID tag further comprises oscillating the antenna module between a near-field scanning mode and a far-field scanning mode, wherein the near-field scanning mode corresponds with activation of the near-field antenna, and wherein the far-field scanning mode corresponds with activation of the far-field antenna.
  • the return signal comprises signal strength and phase information associated with the RFID tag.
  • Non-transitory computer-readable storage medium comprising instructions stored therein, which when executed by one or more processors, cause the processors to perform operations comprising scanning, using a transceiver, an RFID tag of a wireless asset, wherein the transceiver comprises an antenna module including a near-field antenna and a far-field antenna, receiving one or more return signals from the RFID tag, and determining a location of the wireless asset based on the one or more return signals.
  • the near-field antenna is a subset of the far-field antenna.
  • the processor is further configured to perform operations comprising receiving two or more return signals from the RFID tag and determining a direction of the wireless asset based on the two or more return signals.

  • RF radio-frequency
  • access control system 100 is not illustrated with respect to any specific implementation, by means of example, such an access control system may be used for purposes such as asset tracking in a factory, warehouse, or other commercial building, wherein integrated or externally attached RFID tags are used to track the flow of packages or other goods, or for a building security system, wherein RFID tags are embedded into identification cards and used to verify and grant individual access to locked doors or other secured assets.
  • cloud controller 102 is communicatively coupled with each of the access control readers 110a-110n via a direct link, although in some embodiments, cloud controller 102 may be communicatively coupled with one or more of the access control readers 110a-110n via an indirect link, wherein one or more intermediate nodes or access control readers are communicatively coupled between cloud controller 102 and the destination access control reader.
  • communicatively coupled is understood to mean any data transmission link between two or more computing devices or components, wired or wireless. Examples of such data transmission links include, but are not limited to, a Local Area Network (LAN), a Wide Area Network (WAN), Intranet, Internet, or any other wired or wireless networking and data transmission technologies that are known in the art.

  • cloud controller 102 may be located on a separate network from that of the access control readers 110a-110n, such that both networks much be breached or otherwise compromised in order for access control system 100 to be defeated.
  • cloud controller 102 may be physically remote from access control readers 110a-110n, which can increase security and provide greater operational flexibility by allowing the access control system 100 to be operated and monitored constantly, for example through a secure web portal or web application.
  • cloud controller 102 is provided in a tiered hierarchy, such that it is above each of the access control readers 110a-110n.
  • cloud controller 102 and the access control readers 110a-110n can exist in a master-slave relationship, wherein cloud controller 102 oversees all aspects of operation for each of the access control readers.
  • cloud controller 102 is not limited to such a master-slave relationship, and it is understood that the access control readers may be capable of a partial or total degree of autonomy in their operation (provided, for example, via controller 112 contained within access control reader 110a), such that cloud controller 102 only assumes a supervisory role, such as monitoring for any abnormal events or other deviations from expected operation.
  • Cloud controller 102 may be provided on a single computing device, such as a computer server, or cloud controller 102 may be provided across a plurality of different computing devices that comprise, for example, a cloud computing cluster.
  • cloud controller 102 may be implemented as a central processing unit (CPU), a microcontroller (MCU), a microprocessor, integrated circuitry, or any other controller known in the art.
  • cloud controller 102 may be connected to a database (not shown) that can store historical records of each interaction between the plurality of RFID tags 120 and the access control readers 110a-110n.
  • the database may also be used to store one or more access control policies, with a specific access control policy being manually selectable (and editable) by an administrator of access control system 100, or being automatically selectable according to one or more pre-defined rules, based on criteria such as time or location.
  • access control readers 110a-110n contains some number n of access control readers, that may be physically identically or otherwise capable of providing substantially similar functionality. Each access control reader may be associated with a certain access point, and any given access point may be associated with one or more access control readers. As depicted in FIG. 1 , each of the access control readers 110a-110n is illustrated in an identical schematic form, and the following description will be made with reference to access control reader 110a, but is extensible to each of the access control readers 110a-110n.
  • Access control reader 110a consists of three primary components: a controller 112, a transceiver 114, and a far-field antenna 116.
  • a near-field antenna 118 is formed from a subset of far-field antenna 116, as will be subsequently explained in greater depth.
  • Controller 112 may be provided by a processing element, capable of implementing programmed commands that may be edited or modified by an administrator of access control system 100. In some embodiments, controller 112 may simply receive one or more control commands from cloud controller 102 and execute them accordingly.
  • transceiver 114 is coupled to controller 112, and is capable of transmitting and receiving RF or other electromagnetic (EM) signals, as is understood by one of ordinary skill in the art.
  • the signal processing required to support this transmitting and receiving functionality may be performed by a processing element of controller 112 or a processing element of cloud controller 102
  • transceiver 114 may contain its own signal processing element, particularly in a large access control system where it may be impractical to perform signal processing at controller 112 or cloud controller 102.
  • Transceiver 114 is further coupled to far-field antenna 116, which is used to interact with one or more of the plurality of RFID tags.
  • far-field antenna 116 has an operable range of up to 30 feet, although it is understood that the operable range of far-field antenna 116 may depend upon a number of different factors such as the operating wavelength of access control system 100, the physical geometry of the access point at which far-field antenna 116 is located, the polarization of access control reader 110a and the polarization of a given RFID tag.
  • Near-field antenna 118 is formed from a subset of far-field antenna 116, which may be achieved by selectively energizing a certain portion of far-field antenna 116, as will be explained with respect to FIG. 2 . This selective energization may be controlled by controller 112, cloud controller 102, or some combination of the two. When near-field antenna 118 is energized, it may have an operational range of approximately 18 inches, although once again, it is understood that this operable range may depend upon a number of different factors as would be appreciated by one of ordinary skill in the art. Each of far-field antenna 116 and near-field antenna 118 may interact with one or more of the plurality of RFID tags 120 in order to perform a read operation, and multiple RFID tags may be read simultaneously. In one aspect of the disclosure, access control reader 110a may oscillate between energizing far-field antenna 116 and energizing near-field antenna 118, in order to provide an improved and more reliable tracking of the plurality of RFID tags 120.
  • FIG. 2A-2C three different antenna configurations are illustrated, wherein each of the distinct antenna configurations can be achieved using the same set of physical antenna components, as indicated by the numerical labeling common to the three figures.
  • each configuration is presented in a simplified diagrammatic form, wherein a solid line indicates an energized antenna portion and a dashed line indicates a non-energized antenna portion.

  • FIG. 2B depicts a combined near-field and far-field antenna configuration 200b, in which a near-field loop antenna and a far-field antenna are energized.
  • FIG. 2C depicts a far-field antenna configuration 200c, wherein only a far-field loop antenna is energized.
  • access control reader 110a may oscillate between near-field antenna configuration 200a and combined near-field and far-field antenna configuration 200b. In a second embodiment, access control reader 110a may oscillate between near-field antenna configuration 200a and far-field antenna configuration 200c. The oscillation may take place on the order of 20-200 Hz, wherein a greater oscillation frequency can provide a greater resolution with respect to the movement and position of a given RFID tag in the vicinity of access control reader 110a, although it is understood that other oscillation frequencies may be implemented as needed or as desired for a given application.
  • oscillation controller 208 which is coupled to switches 206a and 206b in order to selectively energize the desired antenna components.
  • Switches 206a and 206b may be mechanical or solid-state switches, depending on the specific application in which they are used.
  • Oscillation controller 208 may be provided by controller 112 or by cloud controller 102, as explained previously. Oscillation controller 208 may also be a standalone component, equipped to receive control or timing commands from one or more of controller 112 and cloud controller 102.
  • switches 206a and 206b are positioned such that only a near-field loop antenna 210 is energized, wherein near-field loop antenna 210 is formed from a series connection between first loop portion 202a, a bridge portion 205, and a second loop portion 202b.
  • FIG. 2A depicts only a single near-field loop antenna 210, some embodiments may make use of one or more near-field loop antennas.
  • the one or more near-field loop antennas may be provided as Ultra High Frequency (UHF) antennas.
  • UHF Ultra High Frequency
  • the distal ends of first loop portion 202a and second loop portion 202b are left unconnected, but in operation, may be connected to a matching or tuning network, as would be understood by one of ordinary skill in the art.
  • first loop portion 202a is connected as a feed and second loop portion 202b is connected as a ground (or vice versa).
  • an RF signal is sent to the feed loop portion. Based on the length and tuning of near-field loop antenna 210, this RF signal is matched such that there is an even current distributed across the loop and then grounded, causing an RF field to be generated.
  • This RF field radiates perpendicular to the center of the loop, to a height that is proportional to the diameter of the loop, thereby defining a three-dimensional read-zone in which near-field loop antenna 210 is able to read an RFID tag.
  • this read-zone may extend approximately 18-24 inches away from one or more of the center of near-field loop antenna 210 or the plane containing antenna 210, but in general is limited to four inches away in the absence of a high-powered near-field antenna.
  • the specific geometry of this RF field or read-zone can be further adjusted by varying the shape and polarity of antenna 210; by varying the current and manner in which it is driven through the loop; and through a variety of other factors as would be appreciated by one of ordinary skill in the art.
  • near-field loop antenna 210 is more ideally situated for applications such as door locks or other applications that will predictably involve contact or close proximity between access control reader 210a and an RFID tag.
  • a read signal received at access control reader 210a can generally be taken to indicate that a given RFID tag (and the individual or object associated with it) is located at an access point controlled by access control reader 210a and is further seeking to enter the access point.
  • near-field loop antenna 210 is useful for performing the actual validating step for granting or denying access to an access point, but due to its limited range and small read-zone, is ultimately ineffective for tracking the movement of assets such as individuals or objects.
  • an access control reader that only makes use of a near-field antenna can only track actual attempts to access the access point.
  • a near-field access control reader can only log the RFID tags that were placed within the read-zone and either granted or denied access.
  • a near-field only access control reader may fail to log any tags and associated assets that are exiting the access point, unless an additional access control reader is installed, creating additional expense and further slowing the rate at which assets may enter and exit the access point.
  • controller 208 adjusts switches 206a and 206b in order to additionally energize (with respect to near-field antenna configuration 200a) a first far-field portion 204a and a second far-field portion 204b, thereby forming a combined near-field and far-field antenna 220.
  • Combined antenna 220 has a far greater operational range than near-field loop antenna 210, capable of reading RFID tags at a range of approximately 30 feet. By virtue of this increased operational range, combined antenna 220 can be used to track RFID tags and their associated assets based on analyzing the signal strength of the return signal transmitted by a given RFID tag, where a given signal strength can be mapped to or otherwise correlated with a specific distance from the combined antenna 220.
  • a single reading is often not helpful when taken in isolation, due to inherent challenges in far-field readings. For example, a return signal may experience unaccounted for attenuation if it passes through any medium other than air while traveling on a path between an originating RFID tag and a receiving antenna or access control point.
  • a return signal may experience multiple reflections before being received at an antenna or access control point. In both of these cases, the signal strength of the received return signal will be lower than what would otherwise be expected at the given distance between the originating RFID tag and receiving antenna or access control point, leading to an over-estimation of distance.
  • phase information associated with the return signal transmitted by the given RFID tag may be analyzed, either alone or in combination with the signal strength, as the phase information may be less affected by any attenuation effects in comparison to the signal strength.
  • each reading of a given RFID tag can be saved at one or more of the access control reader and cloud controller 102, and likewise, the average distance calculation can be performed at one or more of the access control reader and cloud controller 102.
  • a velocity or direction of the RFID tag and associated asset may also be calculated or approximated by analyzing a change in position or distance with respect to time. Such information can be useful, for example, in determining whether an RFID tag and its associated asset are approaching or moving away from an access point and access control reader. This determination may also be simultaneously made for one or more RFID tags and their associated assets, which can improve security by tracking and accounting for all assets entering or exiting the access point, rather than only tracking and accounting for the asset that presented an RFID tag for verification and authorization at the access control reader.
  • access control readers operable in only the near-field are vulnerable to what is commonly referred to as a "walk behind", wherein an authorized user may present an RFID tag to gain entrance to an access point such as a building and then allow other users, whether authorized or unauthorized, to enter at the same time.
  • cloud controller 102 may be adapted to predict the movement or flow of assets on the basis of this position and velocity or direction data, which can prove critically important for scenarios such as alerting security personnel to a predicted attempt to enter a geo-fenced or otherwise restricted zone within an access control system.
  • this predictive data may be used to avoid or reduce bottlenecks in the flow of assets, whether humans or objects, which are passing through an access point, by either re-routing assets or providing increased throughput at the access point.
  • a far-field antenna is provided in a fixed or static configuration within an access control reader, then so too is the polarity of the far-field antenna fixed or static (although some embodiments may provide for a variable far-field antenna polarity, at additional expense and complexity).
  • a far-field antenna may be provided with a fixed horizontal polarization.
  • Such a horizontally polarized far-field antenna can generally read a horizontally polarized RFID tag at close range, including the 4-24 inch read-zone provided by the previously discussed near-field antenna 210.
  • a horizontally polarized far-field antenna cannot reliably or predictably read a vertically polarized RFID tag at close range, and will often fail to obtain any reading whatsoever when such a polarization offset exists between the RFID tag and far-field antenna.
  • a failure to obtain a reading is unacceptable, and consequently, security-oriented access control readers rely solely upon near-field antennas, choosing a limited, but reliable, feature set over the enhanced, but sometimes unreliable, tracking features enabled by far-field antennas.
  • the presently disclosed access control system obviates any such issue or decision by providing a near-field antenna 210 that is a subset of a larger far-field antenna and oscillating between the two - thereby coupling the enhanced tracking and prediction of the far-field antenna with the high reliability of the near-field antenna.
  • an access control system of the present disclosure can perform 100 near-field reads every second, using near-field antenna configuration 200a, and 100 far-field reads every second, using combined near-field and far-field antenna configuration 200b or far-field antenna configuration 200c.
  • the access control system may use other read frequencies, or other read patterns.
  • the access control system may perform a read pattern of five consecutive far-field reads and then one near-field read, wherein the read pattern is not limited to any specific read frequency.
  • a read pattern may be desirable in environments with a large number of assets to be tracked in the far-field, particularly when viewed in comparison to the number of assets to be tracked in the near-field.
  • Far-field antenna configuration 200c is largely identical to combined near-field and far-field antenna configuration 200b, with the difference being bridge portion 205, which is not energized in far-field antenna configuration 200c.
  • Far-field antenna configuration 200c can provide the exact same functionality as that of the combined near-field and far-field antenna configuration 200b, described above, for example, achieving an operating range of approximately 30 feet.
  • far-field antenna configuration 200c suffers from more pronounced difficulties and unreliability when reading RFID tags at short-range.
  • FIG. 3 illustrates a method 300 of tracking wireless assets by using a switchable, oscillating near-field and far-field antenna.
  • a far-field antenna is energized and used to transmit a scan signal into the area immediately surrounding the far-field antenna.
  • this far-field antenna may be coupled to or otherwise associated with a transceiver of an access control reader, and the access control reader may further be installed at an access point.
  • the scan signal propagates through the nearby area, with an effective range of approximately 30 feet from the point of transmission.
  • the scan signal is received by one or more RFID tags that are within the effective range of the far-field antenna.
  • each RFID Upon receiving the scan signal, each RFID then transmits a unique return signal containing identification information and any other data that may be stored on the RFID tag.
  • passive RFID tags may be used, capturing energy from the received scan signal and using it to broadcast the return signal into the area immediately surrounding the RFID tag.
  • the transceiver receives return signals from the one or more RFID tags that received the scan signal of step 302. Using at least the information contained in the return signal, the location of a wireless asset associated with a given RFID tag is determined. For example, the signal strength of the return signal can be analyzed to determine a distance between the given RFID tag and the transceiver, and this distance can then be translated into a location.
  • a velocity or direction of a wireless asset associated with a given RFID tag is determined by analyzing a change in its location with respect to time.
  • the velocity or direction calculation can be used to predict a future position or destination of the wireless asset associated with the given RFID tag.
  • a near-field portion of the far-field antenna is energized, and transmits a near-field scan signal into the area immediately surrounding the near-field portion of the far-field antenna.
